of lead powder in 40 gallons of water. Apply the liquid as soon as the leaves 

 are well developed on currants or just before the red currants come into bloom, 

 and take special precautions to spray thoroughly the central and lower part 

 of the bush ; because this is where the young larvae feed for a week or more after 

 hatching. If Bordeaux mixture is used, arsenate of lime, a little weaker than 

 either of the above strengths of arsenate of lead, may be used, or Paris green 

 may be substituted at the strength of not more than one-quarter of an ounce 

 to 40 gallons of the Bordeaux. Usually one good spraying is quite sufficient. 

 If a second one is given, it should be about eight or ten days after the first, or 

 soon after the red currants are well set. 



It may be worth mentioning in closing that Bordeaux mixture is a most 

 valuable fungicide for currants, both red and black, and has the effect of pre- 

 venting the foliage from dropping prematurely. In this respect it is much 

 superior to lime-sulphur or the soda-sulphur compounds, and also to any of 

 the sulphur or Bordeaux dusts that the writers are familiar with. 



EAST KOOTENAY DIPTERA. TIPULID^— I. 



BY C. B. D. GARRETT, 

 Cranbrook, B.C. . 

 Under the admirable leadership of Dr. C. P. Alexander I have been doing 

 some work on the Kootenay Tipulidae. The work has but started, but small 

 as itis,the list of specimens is of some interest, for it contains three forms hitherto 

 unknown from Canada. These are Dicranoptycha sobrina Will., Tipula dorso- 

 lineata Doane and Rhaphidolahis neomexicana Al. The last is interesting, hav- 

 ing been previously taken only at two localities in Colorado and one in New 

 Mexico. The capture of Stygeropis fuscipennis Lw. also upsets the view that 

 it is only a late season flyer, since in the Kootenays it is on the wing from May 

 7th until July 14th. 



~ It is unfortunate that most of the captures have been females only, as these 

 are, in many cases, difficult to determine, but later males will probably be 

 taken, and doubtful names verified or corrected. 

 The list as it stands is as follows: —
